I have the exact problem as addressed in this forum: http://forums.b2evolution.net/viewtopic.php?t=8737&highlight=login and tried to fix it by using this link: http://evocms.cvs.sourceforge.net/evocms/b2evolution/blogs/inc/MODEL/sessions/_session.class.php?r1=1.11.2.4&r2=1.11.2.5 but nothing changes and the login page keeps on loading without logging in. Do you have any more suggestions?
